[qt5-base] libx11-xcb-dev is not the only package required for the GUI components #11727

davidebeatrici · 2020-06-02T23:57:33Z

The port warns the user that libx11-xcb-dev is required, but it's not the only dependency.

Qt's build system skips targets it doesn't find the dependencies for, resulting in the Xcb platform plugin not being compiled. Without this plugin GUI applications cannot work:

qt.qpa.plugin: Could not find the Qt platform plugin "xcb" in ""
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Aborted (core dumped)

This is what I ultimately had to do to resolve the issue:

sudo apt install libxkbcommon-dev
sudo apt install '^libxcb.*-dev' libx11-xcb-dev libglu1-mesa-dev libxrender-dev libxi-dev

../Qt/5.12.4/Src/configure -static -prefix ~/qt-5124 -system-xcb -recheck-all

Note:
I had a build directory that I used for an interim build location: ~/qt-5124-build. In that directory, there were two very useful file:
config.log
config.summary

I'm not sure whether all packages are actually needed, but I can confirm that installing them results in the plugin being compiled on Ubuntu 18.04. On 16.04 too, but it's not supported by Qt anymore.

If Qt is built as static, the plugin has to be linked to the target in CMake:

if(TARGET Qt5::QXcbIntegrationPlugin)
	include_qt_plugin(my_app PRIVATE QXcbIntegrationPlugin)
	target_link_libraries(my_app PRIVATE Qt5::QXcbIntegrationPlugin)
endif()

include_qt_plugin() can be found at https://github.com/davidebeatrici/mumble/blob/cmake/cmake/qt-utils.cmake.

Unfortunately applications crash as soon as Qt tries to load the fonts, after freezing for a few seconds.

@Neumann-A Could you please take a look?

Thanks.

@JackBoosY: related: 6b10332
I thought about adding all those libs to the message but the message becomes very long. I thought about just adding a hint to https://doc.qt.io/qt-5/linux-requirements.html
About the Font issue: Maybe some other qt plugins are missing? I would first retry to switch to 5.14 or try the 5.15 PR since there plugin integration in static builds is automatic. Otherwise try switching all of Qt to dynamic library linkage.

davidebeatrici · 2020-07-14T17:53:02Z

I'm building Qt again now that #11596 is merged.

For reference: the portfile initially failed to build during the configure step because libxkbcommon-x11-dev was not installed.

Neumann-A · 2020-07-14T19:09:09Z

As long as you are on ubuntu 18.04 you should be fine. on 20.04 we need to update or fix our fontconfig first to make it work.
Unfortunately Qt requires a bunch of system libraries:

Unfortunately qt5-declarative fails to build:
package-build-x64-linux-dbg-err.log

JackBoosY · 2020-07-15T02:06:16Z

@Neumann-A Seems the compiler can't open many json files.

Neumann-A · 2020-07-15T07:38:31Z

@davidebeatrici: Have you retried? I cannot find an error in there which is not a killed 9. Either you killed the process or your system killed the process. https://stackoverflow.com/questions/726690/what-killed-my-process-and-why

@JackBoosY: I think the *.json failures can be ignored. It seems like it is a new feature of qt to export json files for metatypes which is not yet fleshed out. On my machine (WSL2) qt5-declarative builds fine despite the missing files.

Neumann-A · 2020-07-15T07:59:24Z

@JackBoosY: since qt5network_metatypes.json would be generated by qt5-base here is a file list of arch_linux for qt5-base 5.15. It also does not contain the file. https://www.archlinux.org/packages/extra/x86_64/qt5-base/files/

davidebeatrici · 2020-07-15T17:45:04Z

@Neumann-A I initially thought it was due to the virtual machine's RAM being full, however after increasing it and retrying multiple times the behavior didn't change.

Only qt5core_metatypes.json, qt5gui_metatypes.json and qt5widgets_metatypes.json are generated.

Neumann-A · 2020-07-15T18:07:03Z

Only qt5core_metatypes.json, qt5gui_metatypes.json and qt5widgets_metatypes.json are generated.

@davidebeatrici That seems to be normal. Since in a successful built only those exists and those also are the only ones in the arch linux filelist. If the process is killed you have to find out why it is killed. The logs do not indicate a problem.

davidebeatrici · 2020-07-15T21:55:57Z

Sorry, I missed the second part of your message.

I tried to lower the thread count from 8 to 4, but ld still gets killed.
I'm going to increase the physical RAM so that I can assign more GB to the VM and let you know how it goes.

JackBoosY · 2020-07-17T05:59:48Z

@davidebeatrici Any progress?

davidebeatrici · 2020-07-17T17:42:16Z

@JackBoosY Waiting for the RAM sticks to arrive.

davidebeatrici · 2020-07-27T20:53:51Z

Now that I assigned 16 GB and 8 threads to the VM Qt successfully built, but unfortunately I'm encountering the exact same issue:

Neumann-A · 2020-07-28T05:08:45Z

No that is probably an issue with fontconfig not correctly setup. If this is Ubuntu 20.04 you cannot use vcpkgs Qt currently because an update to fontconfig is required. You could try manually setting up the fontdatabase with the fontconfig version of vcpkg but this requires knowledge on how to set that up (and a way to build fc-cache). you could try #11776 which updates fontconfig and generates a valid fontconfig conf file and database. (You still need to set environment var FONTCONFIG_FILE to point to the generated config though)

Sorry, I didn't mention that I'm currently building and testing the environment on Ubuntu 18.04:

Does your suggestion apply to this version of Ubuntu as well?

Recent vcpkg upgrade --no-dry-run to 5.15 and I am able to compile our project in up to date Debian 10 (Buster). I ran sudo apt-get build-dep qt5-default to address issues with any dependencies in Debian. When I launch our project there is no text in the menus at the root or sub level. There are several Fontconfig errors and warnings similar to this report:

https://bbs.archlinux.org/viewtopic.php?id=235643

I'm not sure that a 32 bit package should be the cause but they do point out possible version issues or changes.

Neumann-A · 2020-08-20T21:07:32Z

When I launch our project there is no text in the menus at the root or sub level.

That is probably due to fontconfig in vcpkg being outdated. should be fixed by #11776

kafeg · 2020-08-24T09:41:06Z

Hey all! I had the same problem.

There is a dirty solution to fix crash inside fontconfig on FcFileScanFontConfig. You could use this CONTROL and portfile.cmake to replace your own files in fontconfig port and rebuild it. After that Qt5 GUI apps will work correctly:

CONTROL

Source: fontconfig
Version: 2.8.0
Homepage: https://www.freedesktop.org/software/fontconfig/front.html
Description: Library for configuring and customizing font access.
Build-Depends: freetype, expat, libiconv, dirent

portfile.cmake

include(vcpkg_common_functions)

set(FONTCONFIG_VERSION 2.8.0)
vcpkg_download_distfile(ARCHIVE
    URLS "https://www.freedesktop.org/software/fontconfig/release/fontconfig-${FONTCONFIG_VERSION}.tar.gz"
    FILENAME "fontconfig-${FONTCONFIG_VERSION}.tar.gz"
    SHA512 a110e72cc631f1e374324a02f6ba9526b89a547cafe2ae27b9913938b19018843b2940084d62f0dfaf38a6919dea6974fb98422d3908026f6873d5fba17c55a0
)

vcpkg_extract_source_archive_ex(
    OUT_SOURCE_PATH SOURCE_PATH
    ARCHIVE ${ARCHIVE}
    REF ${FONTCONFIG_VERSION}
)

set(ENV{LDFLAGS} "${VCPKG_LINKER_FLAGS} -L${CURRENT_INSTALLED_DIR}/lib/")
set(ENV{LIBS} "$ENV{LIBS} -lfreetype -lbz2 -lpng -lz -lm")

vcpkg_configure_make(
    AUTOCONFIG
    SOURCE_PATH ${SOURCE_PATH}
    OPTIONS --disable-docs --enable-static --with-freetype-config=no
)

vcpkg_install_make()

file(REMOVE_RECURSE "${CURRENT_PACKAGES_DIR}/debug/var" "${CURRENT_PACKAGES_DIR}/debug/lib/pkgconfig" "${CURRENT_PACKAGES_DIR}/var" 
                    "${CURRENT_PACKAGES_DIR}/share/fontconfig/man1" "${CURRENT_PACKAGES_DIR}/debug/share")

vcpkg_fixup_pkgconfig()

file(COPY ${SOURCE_PATH}/COPYING DESTINATION ${CURRENT_PACKAGES_DIR}/share/fontconfig)
file(RENAME ${CURRENT_PACKAGES_DIR}/share/fontconfig/COPYING ${CURRENT_PACKAGES_DIR}/share/fontconfig/copyright)

As you could see, i downgraded fontconfig from 2.12 to 2.8.0 which could be used to build Qt 5.12.* and changed build from cmake-based to standard configure, make way.

@Neumann-A @JackBoosY @davidebeatrici

PS: I also tried the newest version from #11776 but it doesn't' work for me because i can't compile it.

davidebeatrici · 2020-08-24T23:58:01Z

@kafeg I confirm it works, thank you very much!

Please note that I had to link to the Brotli libraries:

set(ENV{LIBS} "$ENV{LIBS} -lfreetype -lbz2 -lpng -lz -lm -lbrotlidec-static -lbrotlicommon-static")

Otherwise:

/home/user/vcpkg/installed/x64-linux/lib//libfreetype.a(sfnt.c.o): In function `woff2_open_font.isra.18':
sfnt.c:(.text+0xc055): undefined reference to `BrotliDecoderDecompress'
collect2: error: ld returned 1 exit status

JackBoosY · 2021-02-07T08:50:11Z

Hi guys, since #11776 was merged, does this issue resolved?

Krzmbrzl · 2021-02-13T14:26:45Z

I am currently in the process of performing some tests with regards to this. Should get results in the upcoming days... ☝️

davidebeatrici · 2021-02-16T12:13:35Z

@JackBoosY Sorry for the delay.

I just checked and the issue appears to be completely fixed.

Krzmbrzl · 2021-02-17T07:08:44Z

I can confirm that it is working fine now 👍
